There
is
a
setting
which
edge
should
be
counted
at
the
counter
‐
function.
If
you
select
“Count
rising
and
falling”,
the
counter
will
count
for
toggling
two
switching
processes.
If
only
the
rising
or
the
falling
edge
should
be
counted,
the
counter
will
count
only
one
switching
process
for
toggling.
The
sending
difference
adjusts
when
the
counter
should
send
a
value.
When
you
have
for
example
adjusted
10
as
sending
difference,
the
counter
will
count
every
switching
process
but
send
its
value
only
at
reaching
10.
The
communication
object
“reset
counter”
sets
the
counter
back
to
0.
This
communication
object
reacts
as
well
to
a
“0”
as
to
a
“1”.
The
following
diagram
shows
the
function
of
the
counter
with
the
setting
“count
rising
and
falling”
and
a
sending
difference
of
5.
At
this
example,
the
counter
sends
only
a
value,
when
the
counter
value
is
a
multiple
of
the
sending
difference.
So
the
counter
value
is
a
continual
rising
value
and
the
output
value
a
periodic
rising
value.
As
soon
as
the
group
address,
in
which
the
communication
object
“reset
counter”
is
connected
to,
is
addressed
with
a
logical
“0”
or
a
logical
“1”,
the
counter
value
as
well
as
the
output
value
will
be
set
back
to
0.
